Burned Board: Has The Board Failed?
How much does a new furnace circuit board cost?
A furnace circuit board replacement can cost between $550 - $1,100, depending on how complex your system is.
Can a burned circuit board be repaired?
Nevertheless, the damage can be repaired and the board restored to it original integrity - and even appearance - by the following procedure. Some specialized tools are needed, and the liquid epoxy repair material can even be colored, with color agents to replicate the color of the surrounding original board material.
How long should a furnace control board last?
A furnace circuit board lasts 10 to 15 years on average, depending on the furnace condition, usage, and level of maintenance.

How do I know if my furnace board is bad?
Use some tape to keep the switch pressed down. If your control board has 120 volts AC going into it, then it has power. If your control board has power, but it's diagnostic light is not on, then the control board is likely bad and needs to be replaced. NOTE: You'll need a multimeter to test for power in your furnace.
